Hi...i am a new user here. In my case i used a TIP122 transistor to switch the polarity of a fuel pump relay. It's been working now for 2 years so reliability is not an issue. Switching speed might be another issue. If it wont drive off the stock tach output you can run all 3 coil negatives out from under the coils through a diode each to stop them all triggering at once aand join them together to feed technology.
